Create Custom Big Objects from Setup

A big object stores and manages a massive amount of data natively on
the Salesforce platform. You can archive data from other objects or bring massive datasets
from outside systems into a big object to get a full view of your customers. Big objects
provide consistent performance, whether you have 1 million records, 100 million, or even 1
billion. Previously, creating a big object required using Metadata API. But now, if you aren’t
comfortable using the API, you can create a big object in Setup, define its fields, and build
the index that defines how the big object is queried.

Where: This change applies to Lightning Experience and Salesforce Classic.

How: From Setup, enter Big Objects in the Quick Find box, then
select Big Objects. Click New, and the wizard
guides you through the steps.
